Final answer:
Nalani Burrows' total investment amount consists of the initial purchase cost of the 100 shares plus the purchase commission, and the net profit from the sale of the shares after paying the sale commission. The total purchase cost was $1,530, and she sold the shares for a total of $2,475 after commission. Her net profit from this investment was $945.
Step-by-step explanation:
To calculate the total investment amount for Nalani Burrows, we need to consider both the purchase and sale of the shares. Originally, Nalani bought 100 shares at $15.00 each, which amounts to $1,500 for the shares themselves. Additionally, she paid a $30 commission for the purchase. So the total purchase cost is:
$1,500 (for shares) + $30 (purchase commission) = $1,530
When she sold the shares, the selling price was $25.00 per share for 100 shares, totaling $2,500. A $25 commission was paid on the sale. So the total sale cost is:
$2,500 (from the sale of shares) - $25 (sale commission) = $2,475
The net profit from the transaction is the total sale cost minus the total purchase cost:
$2,475 (total sale cost) - $1,530 (total purchase cost) = $945
Nalani's Total Investment Amount
It's important to note that while the question asks for the total investment amount, based on the context it seems to be asking for the net gain from the investment. If that's the case, the net profit of $945 is what Nalani earned from her investment.
